Ein Mädchen aus Ban Alm stellt mit Hilfe eines Bambusbogens aus rotem Baumwollfaden und weißen Samenkernen (Cois lacryma jobi) eine an beiden Enden mit Quasten versehene Zierschnur her.

Two threads with white seed pearls and two strings consisting of seven cotton threads each are strung on a bamboo bow in the manner of a warp. A red cotton thread is passed through the warp by hand. Thus a ribbon is made the edges of which are formed by the two rows of pearls. The end of the ribbon is finally decorated with a tassel of variously coloured cotton threads.
